Email design system

Helium — email design system

A complete system of clean, high-performing email templates. Built with strong typography, clear structure, and reusable blocks for both transactional and marketing emails.

A complete system, not just templates

Helium is not a collection of random layouts. It’s a structured system you can use consistently across all your emails from product notifications to campaigns.

A minimal and practical color setup. Works in both light and dark environments without breaking contrast or readability.

Guidelines that explain what works

Helium doesn’t just give you templates it shows how to use them. Clear rules for typography, layout, grid, CTAs, and images help you build better emails over time.

Email system guidelines

Typography that makes emails readable

Clear hierarchy, balanced spacing, and carefully chosen sizes. Helium focuses on text-first emails that are easy to scan and comfortable to read.

Built for easy customization

All styles are structured through variables. You can adapt colors, spacing, and typography quickly without breaking the system.

components and reusable blocks

Build emails from clear, predictable pieces. Headers, text blocks, features, CTAs, footers — everything is designed to work together and stay consistent.
